The BMW ALPINA B3 S BITURBO: Why is it not in the States?

There are some rare automatics that are worth it. This ALPINA S B3 BITURBO is an automatic equipped much enhanced BMW 335i that is very pleasing to the eye. And with an increase of 100 horsepower and 100 ft-lbs of torque it's not just a pretty face. The real problem is you cannot buy one here! These vehicles are only sold in Europe, the Middle East and parts of Asia. I believe these cars would be a great addition to the BMW lineup here in the states.
